According to OP:
MUGEN 1.0 & 1.1 ONLY!
Just a test for april fools' day. This character is the very first Whale-Tier character for 1.X.
It is recommended to use DirectX as a rendermode to
get the full experience.
OpenGL works, but it starts during the round and can be defeated
if the opponent uses powerful technologies.
It is likely that from the first startup, after just putting
in the roaster the character crashes. Select it and if it
crashes, restart MUGEN and then it should always work.
